Ingredients
This Old Southern Chocolate Pecan Sheet Cake requires a combination of pantry staples and fresh ingredients that work together to create both the moist chocolate cake base and rich frosting. The recipe calls for basic baking essentials like flour, sugar, and eggs, along with cocoa powder that provides the deep chocolate flavor throughout both the cake and frosting layers.
For the Cake:
- 2 cups white sugar
- 2 cups all-purpose flour
- ½ teaspoon salt
- 1 cup water
- ½ cup vegetable shortening
- ½ cup margarine
- 3 tablespoons unsweetened cocoa powder
- 1 teaspoon baking soda
- ½ cup buttermilk
- 2 eggs, beaten
- 1 teaspoon vanilla extract
For the Frosting:
- 1 (16 ounce) box confectioners’ sugar
- 3 tablespoons unsweetened cocoa powder
- ½ cup butter
- 6 tablespoons milk
- 1 teaspoon vanilla extract
- 1 cup chopped pecans
When preparing your ingredients, make sure the eggs are at room temperature for better mixing, and have your pecans chopped to a uniform size for even distribution throughout the frosting. The combination of vegetable shortening and margarine in the cake creates the signature moist texture that defines this Southern classic, while fresh pecans will provide the best flavor and crunch in the finished dessert.
Directions
Begin by preheating your oven to 350°F (175°C) and greasing a 9×13-inch baking pan. In a large mixing bowl, whisk together 2 cups white sugar, 2 cups all-purpose flour, and ½ teaspoon salt. In a medium saucepan, combine 1 cup water, ½ cup vegetable shortening, ½ cup margarine, and 3 tablespoons unsweetened cocoa powder. Bring this mixture to a rolling boil, stirring constantly to make sure the fats melt completely and the cocoa dissolves smoothly. Remove from heat and immediately pour the hot mixture over the dry ingredients, stirring until well combined. In a small bowl, dissolve 1 teaspoon baking soda in ½ cup buttermilk, then add this along with 2 beaten eggs and 1 teaspoon vanilla extract to the batter. Mix thoroughly until the batter is smooth and well incorporated, then pour into the prepared pan and bake for 20-25 minutes, or until a toothpick inserted in the center comes out clean.
While the cake is baking, prepare the frosting by combining 1 (16 ounce) box confectioners’ sugar and 3 tablespoons unsweetened cocoa powder in a large bowl. In a small saucepan, heat ½ cup butter and 6 tablespoons milk until the butter melts and the mixture just begins to simmer. Pour the hot butter mixture over the sugar and cocoa, then add 1 teaspoon vanilla extract and beat until smooth and creamy. Stir in 1 cup chopped pecans. The key to this Southern-style sheet cake is applying the frosting while the cake is still warm – this allows the frosting to penetrate slightly into the cake surface, creating the signature fudgy texture. Spread the pecan frosting evenly over the warm cake and allow it to cool completely before cutting into squares for serving.
Substitutions and Variations
While this traditional recipe delivers authentic Southern flavors, you can easily customize it to suit your preferences or dietary needs. For nut free alternatives, simply omit the pecans or substitute with chocolate chips or coconut flakes. You’ll achieve equally delicious results without compromising texture. For vegan swaps, replace eggs with flax eggs, use plant-based milk instead of buttermilk, and substitute vegan butter for all dairy ingredients. Coconut oil works well in place of vegetable shortening. These modifications won’t affect the cake’s rich, moist consistency that makes this dessert so beloved throughout the South.
Additional Things To Serve With This Dish
Several complementary accompaniments can elevate your chocolate pecan sheet cake from a simple dessert to an impressive finale. A dollop of freshly whipped cream provides a light contrast to the rich chocolate frosting. You’ll find vanilla ice cream creates a delightful temperature contrast against the cake’s dense texture. Coffee pairings work exceptionally well—try serving alongside dark roast coffee, espresso, or even coffee-flavored liqueur for adults. Fresh berries like strawberries or raspberries add brightness that cuts through the sweetness. Consider drizzling caramel sauce over individual slices for extra indulgence that complements the pecans beautifully.
Final Thoughts
This Old Southern Chocolate Pecan Sheet Cake represents everything wonderful about traditional comfort desserts—it’s rich, satisfying, and surprisingly simple to make. You’ll find this recipe becomes part of your family tradition, passed down through generations who appreciate authentic Southern flavors. The beauty lies in its recipe evolution—while maintaining classic ingredients like buttermilk and pecans, you can adapt it to modern kitchens and dietary needs.
